Android---Tween动画示例（XML定义的动画）

1、在res/anim目录下新建XML文件：tween_anim.xml

[html]
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <alpha
        android:fromAlpha="0.2"
        android:toAlpha="1.0"
        android:duration="3000"
        android:repeatMode="reverse"
        android:repeatCount="10" />
    <scale
        android:fromXScale="0.2"
        android:toXScale="1.0"
        android:fromYScale="0.2"
        android:toYScale="1.0"
        android:pivotX="50%"
        android:pivotY="50%"
        android:duration="3000"
        android:repeatMode="reverse"
        android:repeatCount="10" />
    <translate
        android:fromXDelta="50"
        android:toXDelta="100"
        android:fromYDelta="50"
        android:toYDelta="100"
        android:duration="3000"
        android:repeatMode="restart"
        android:repeatCount="10" />
    <rotate
        android:fromDegrees="0"
        android:toDegrees="360"
        android:duration="3000"
        android:repeatMode="restart"
        android:repeatCount="10" />
</set>
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<alpha
  android:fromAlpha="0.2"
  android:toAlpha="1.0"
  android:duration="3000"
  android:repeatMode="reverse"
  android:repeatCount="10" />
<scale
  android:fromXScale="0.2"
  android:toXScale="1.0"
  android:fromYScale="0.2"
  android:toYScale="1.0"
  android:pivotX="50%"
  android:pivotY="50%"
  android:duration="3000"
  android:repeatMode="reverse"
  android:repeatCount="10" />
<translate
  android:fromXDelta="50"
  android:toXDelta="100"
  android:fromYDelta="50"
  android:toYDelta="100"
  android:duration="3000"
  android:repeatMode="restart"
  android:repeatCount="10" />
<rotate
  android:fromDegrees="0"
  android:toDegrees="360"
  android:duration="3000"
  android:repeatMode="restart"
  android:repeatCount="10" />
</set>
2、在res/layout目录下新建XML文件：tween_anim_layout.xml

[html]
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <ImageView
        android:id="@+id/imgTween"
        android:src="@drawable/c01"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:layout_weight="1.0" />
    <Button
        android:id="@+id/btnControl"
        android:text="开始"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</LinearLayout>
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
  android:id="@+id/imgTween"
  android:src="@drawable/c01"
  android:layout_height="wrap_content"
  android:layout_width="wrap_content"
  android:layout_weight="1.0" />
<Button
  android:id="@+id/btnControl"
  android:text="开始"
  android:layout_width="match_parent"
  android:layout_height="wrap_content" />

</LinearLayout>
3、Activity里面添加代码：

[java]
package com.bison;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.Button;
import android.widget.ImageView;

public class TweenAnimationDemo extends Activity {
    // 声明一个开始停止的标识符
    private boolean flags = true;
    private ImageView imgTween;
    private Button btnCtrl;

    /** 初始化 */
    public void init() {
        imgTween = (ImageView) findViewById(R.id.imgTween);
        //
